About Brup Suite

It is a versatile platform designed for probing and testing the security of web applications.

Acting as a middleman between your browser and the web server, it lets you catch, inspect, and tweak data as it flows back and forth.

Security researchers, ethical hackers, and bug bounty participants rely on Brup Suite to uncover risks like injection flaws, cross-site scripting, and authentication gaps.

You can use it for both automated scans and hands-on investigation, making it adaptable to any workflow.

The tool comes in several versions: Community (free for all), Professional (for advanced users), and Enterprise (for teams).

Main Features

Intercepting ProxyThe core of Brup Suite is its intercepting proxy, which lets you watch and modify every request and response between your browser and the target site. For example, you can pause requests, analyze their content, and make changes before sending them along. This gives you a unique perspective on how your application communicates.
RepeaterWith the repeater, you can send the same request over and over, tweaking details each time to see how the server reacts. This is especially useful when you want to test various inputs or payloads.
IntruderIntruder is built for automation. Use it to blast through login forms, search for weak points, or fuzz parameters with custom payloads. Not only does this save time, but it also increases your chances of finding hidden vulnerabilities.
ScannerIf you’re using the paid versions, the scanner can automatically hunt for common vulnerabilities in seconds. Consequently, you can catch issues like SQL injection or cross-site scripting without manual effort.
BApps and ExtensionsExtensions, known as BApps, allow you to add new tools or integrations, so your toolkit can grow with your needs. For instance, you might add a plugin for automated reporting or integration with other security tools.
Other ModulesOther helpful modules include the sequencer (analyzes randomness), decoder (handles encoding/decoding), and comparer (finds differences in requests or responses). Therefore, it becomes a one-stop solution for many web testing tasks.

Linux Installation Steps

Download the installer from PortSwigger’s official site.
Open your terminal by pressing CTRL + T and make the file executable:
chmod +x burpsuite_community_linux.sh
Run the installer:
./burpsuite_community_linux.sh and follow the on-screen instructions.
Once installed, open Brup Suite and set your browser to use the default proxy address (usually 127.0.0.1:8080). This step is crucial for intercepting traffic.
To intercept HTTPS traffic, import the Brup Suite certificate into your browser’s trusted authorities. Without this, secure traffic cannot be analyzed.

That’s it! You’re ready to start testing. Now, you can explore the application and begin your security assessments.

Getting Started with Brup Suite

Enabling the ProxyFire up Brup Suite and make sure the proxy is enabled. Point your browser’s proxy settings to match Brup Suite’s listening address. This connection is the foundation of your testing process.
Intercepting and Modifying TrafficBrowse to your target web app. It will display every request and response, letting you pause, inspect, and modify them as needed.
Experimenting with RepeaterUse the repeater to experiment with requests, changing parameters or headers to see how the server responds. This approach makes it easy to identify potential vulnerabilities.
Automated ScanningIf you have access to the scanner, select a request and let it check for vulnerabilities automatically. As a result, you save time while ensuring thorough coverage.
Using Intruder for AutomationThe intruder module is perfect for automating repetitive attacks or testing large sets of data. Therefore, you can focus on analyzing results instead of manual input.
Generating ReportsWhen you’re done, generate a report to document your findings or share them with your team. This step is essential for communicating results and planning remediation.

Pro Tips for Advanced Users

Learn keyboard shortcuts for faster module switching and request sending.
Explore the BApp Store for add-ons that extend it’s capabilities. New plugins are released regularly.
Set up custom rules to automate repetitive tasks and reduce human error.
